Shield connector

Abstract

A terminal metal piece connected to an electric wire is inserted into a housing and an outer periphery of the housing is attached with a shield shell fixedly attached to a distal end of a shield member surrounding electric wires. Even when the electric wire is bent to be deviated from the regular wiring path, a resin cover is protected against interference with the shield shell by an outer cylinder portion. Further, a mode of protecting the resin cover against interference with the shield shell includes a case in which the resin cover is prevented from being interfered with the shield shell and a case in which even when the resin cover is interfered with the shield shell, the resin cover is avoided from being impaired thereby.

1. A shield connector comprising:
 a terminal metal piece connected to an electric wire, an outer periphery of the electric wire being covered with an insulating resin cover, the terminal metal piece being accommodated in a housing; 
 a shield shell made of a metal, the shield shell being fixedly attached to a shield member surrounding the electric wire, the shield shell being attached to an outer periphery of the housing; and 
 a member that includes (i) a radial portion that extends radially outward from the electric wire, (ii) an inner cylindrical wall portion that protrudes from the radial portion and extends along an outer periphery of the electric wire and (iii) an outer cylindrical wall portion that protrudes from the radial portion and is substantially concentric with the inner cylindrical wall portion, the outer cylindrical wall portion being spaced from the inner cylindrical wall portion in a radial direction, such that an empty space is defined between the outer cylindrical wall portion and the inner cylindrical wall portion, 
 wherein the outer cylindrical wall portion serves as a protecting member that protects the insulating resin cover against interference with the shield shell when the electric wire is bent to be deviated from a regular wiring path. 
 
     
     
       2. The shield connector according to  claim 1 , wherein when the electric wire is bent, the electric wire deforms the protecting member and causes the protecting member to interpose between an end face of the shield shell and the resin cover. 
     
     
       3. The shield connector according to  claim 1 , wherein the protecting member is part of a rubber plug holder which prevents a rubber plug, through which the electric wire penetrates, from being drawn out. 
     
     
       4. The shield connector according to  claim 3 , wherein:
 the rubber plug holder includes (i) an inner cylinder portion that extends along an outer periphery of the electric wire and (ii) an outer cylinder portion substantially concentric with the inner cylinder portion, the outer cylinder portion being spaced from the inner portion in a radial direction and extending along an inner periphery of the housing, 
 a rear end of the outer cylinder portion extends rearward beyond a rear end of the shield shell, and 
 the outer cylinder portion serves as the protecting member. 
 
     
     
       5. The shield connector according to  claim 4 , wherein a rear end of the inner cylinder portion is disposed frontward compared to the rear end of the outer cylinder portion. 
     
     
       6. The shield connector according to  claim 1 , wherein the protecting member comprises (i) an extended portion that extends rearward beyond the shield shell and (ii) a reinforcing portion that restricts the extended portion from being deformed. 
     
     
       7. The shield connector according to  claim 6 , wherein the extended portion is formed at a rubber plug holder which prevents a rubber plug, through which the electric wire penetrates, from being drawn out of the housing. 
     
     
       8. The shield connector according to  claim 7 , wherein:
 the rubber plug holder includes (i) an inner cylinder portion that extends along an outer periphery of the electric wire and (ii) an outer cylinder portion substantially concentric with the inner cylinder portion, the outer cylinder portion being spaced from the inner portion in a radial direction and extending along an inner periphery of the housing, 
 the extended portion is configured by the inner cylinder portion and the outer cylinder portion, and 
 the reinforcing portion includes a rib connecting the inner cylinder portion and the outer cylinder portion in a diameter direction. 
 
     
     
       9. The shield connector according to according to  claim 6 , wherein a rear end portion of the extended portion includes a guide face in a taper shape or an arc shape, an internal diameter of the guide face increasing with progression rearward. 
     
     
       10. The shield connector according to according to  claim 2 , wherein the electric wire deforms the protecting member about 90° from an original position of the protecting member. 
     
     
       11. The shield connector according to according to  claim 1 , wherein when the electric wire is bent and caused to push against the protecting member, the electric wire does not contact an edge of the shield shell until an angle of the wire with respect to a peripheral face of the shield shell has decreased to 40° or less. 
     
     
       12. The shield connector according to according to  claim 6 , wherein when the electric wire is bent and caused to push against the protecting member, the electric wire does not contact an edge of the shield shell until an angle of the wire with respect to a peripheral face of the shield shell has decreased to 40° or less.
